machine to be broken. The air compressor pumps, but there are ao many
leaks between it and the end of the hose that more air leaked out of my
tire than got put in. I think I actually lost air on the first tire, so
I gave up and went home.
Luckily, there's a Wawa near my home, so I stopped there, also. This
free air station was in great shape and accurately inflated and checked
the pressure in all my tires.
Lesson learned: check the free air machine to make sure it'll work
before putting the thing near your tires!
My handy dandy meter confirmed that all four tires remained near 40 psi
since June 1, so my fuel economy variations should be blamed on other
forces, such as driving in stop-and-go traffic in town and on my way
home from work.
Things look good this tank. I'll hopefully make it well past 400 miles
before the near empty light comes on, and probably get to about 430
miles this tank before I fill it up tomorrow morning.
